Tv+screen

If there was a TV screen on my head i not only would not have to many friends but also its would show many things such as sports and then how tired i would be or maybe just what i thought of people, probably not the best idea. Now the thing i would not like to show would have been if you were taking a test and it would say on the screen "What is this answer", not something you would want to show your teacher. Also the cool thing would be that when you are reading a book you could sit in front of a mirror and then you would be able to see what you were thinking.
